Abstract
A lightweight multilayer heat reflective concrete cure blanket having a moisture-impervious top outer layer, a moisture impervious bottom outer layer, and the top and bottom layers sealingly connected to each other at the boundaries of the layers to form a moisture impervious chamber between the first and second layers. The chamber includes at least one insulative layer therein, and a heat reflective material is applied to an outer surface of the bottom layer to reflect heat emanating from the concrete when the blanket is placed over the concrete. A protective heat permeable layer is applied over the heat reflective material to protect the heat reflective material from chemicals and dirt in the concrete. In a further embodiment, a second heat reflective material is applied to an inner surface of the upper layer to reflect additional heat which radiates from the concrete through the insulative layer and back towards the concrete.
